From feathers and metres of tulle to millions of handsewn beads, there were countless killer dresses (and let’s not forget the jumpsuits) on The Brownlow red carpet last night.

But not everyone was wearing designer wares last night.

Three Brownlow WAGs decided in favour of ‘op shop couture’ for AFL’s night of nights – and for a very good cause.

D’Arne Finnis, wife of St Kilda Football Club CEO Matt Finnis, Jo Richardson, wife of senior coach Alan Richardson and Karen Massen, partner of Club president Peter Summer bought their $8 gowns straight off the rack from Sacred Heart Mission op shop in South Melbourne.

“They [Sacred Heart] do such an amazing job for the community of St Kilda and both the club and Sacred Heart come from that community and are supported by that community,” Finnis told thePort Phillip Leader.

From a monochrome silk halterneck number to the almost-obligatory sequin Brownlow bling, they stood out on the red carpet for all the right reasons.

On a night where the focus is heavily on the fashion, the trio promoted a message worthy of the spotlight.

Finnish, who also volunteers at the mission's aged-care residence, says not only was the usual months-in-advance preparation made easier by picking her dress and shoes straight from the op shop, but it also made the night even more special.

"I think if you feel good about doing something you look better anyway. I’ve got three young children so [getting ready has] never been something I’ve been able to dedicate a huge amount of time to on the day," she said.

"Hopefully we look lovely too, but we also like to be feeling fantastic about doing something that has a much broader impact than just wearing a nice dress on the night."

The mission helps people who are homeless or living in poverty to find shelter, food care and support.(Post continues after gallery.)
